Means that the African continent was once in the higher latitudes, and in contact with Antarctica, where glaciers form due to the low temperatures in the poles. The continent drifted over time due to tectonic plate movement. Continental drift is powered by the convection current in the mantle of the earth.
Hey there!
The answer would be A. When electrons. move easily through objects
In science, a conductor is a material that permits a flow of energy. A material that allows the flow of charged particles is an electrical conductor. A material that enables the transfer of thermal energy is a thermal conductor or heat conductor.
Hope this helps !
Answer:
Li-F
Explanation:
Hydroxide is a negative ion, which can form ionic bonds with metals, but the bond in hydrogen and oxygen in hydroxide (OH-) is not ionic. It is covalent in nature.
C-C is clearly a covalent bond.
Li-F is an ionic bond.
Bond between H and Cl in H-Cl is covalent in nature. Because of the size difference hydrogen can not act as a cation. So it rather dissociates.
There are two big advantages of using molarity to express concentration. The first advantage is that it's easy and convenient to use because the solute may be measured in grams, converted into moles, and mixed with a volume.
The second advantage is that the sum of the molar concentrations is the total molar concentration. This permits calculations of density and ionic strength
